Answer 1

So if you come this down to find this.. nothing might have worked for you. There is however an easy fix for this. It is obviously because of improper uninstall (probably due to faulty cable connection).

SOLUTION Download SDMaid from play-store, and delete Corpse files (junk files). Re-run application. (But you need to have your device rooted)

Answer 2

Alternatively, delete the emulator and reconfigure it afresh.

Answer 3

I EVENTUALLY FOUND THE SOLUTION FOR INSTALL_FAILED_DEXOPT and INSTALL_FAILED_UID_CHANGED ERROR

After lot of testing a vary of tricks in vain, I eventually found the main solution to solve this sticky problem forever!

I think the problem is caused by an Eclipse bug! , in fact eclipse can not copy and install built APK file just because of a string name(described further)

I should add that when you use tricks on internet such as delete package name folder in data/data you will face a new sticky error "INSTALL_FAILED_DEXOPT"

So lets see how to solve INSTALL_FAILED_DEXOPT and INSTALL_FAILED_UID_CHANGED

In my case, when i check the log cat i noticed below lines:

09-30 19:03:19.882: I/PackageManager(314): Running dexopt on: com.example.searchapp
09-30 19:03:19.921: E/dalvikvm(6129): Invalid name: 'search_‌country_name'
09-30 19:03:19.921: E/dalvikvm(6129): Trouble with item 226 @ offset 0x2094
09-30 19:03:19.921: E/dalvikvm(6129): Cross-item verify of section type 0004 failed
09-30 19:03:19.921: E/dalvikvm(6129): ERROR: Byte swap + verify failed
09-30 19:03:19.961: E/dalvikvm(6129): Optimization failed
09-30 19:03:19.961: W/installd(144): DexInv: --- END '/data/app/com.example.searchapp-1.apk' --- status=0xff00, process failed
09-30 19:03:19.961: E/installd(144): dexopt failed on '/data/dalvik-cache/data@app@com.example.searchapp-1.apk@classes.dex' res = 65280
09-30 19:03:19.961: W/PackageManager(314): Package couldn't be installed in /data/app/com.example.searchapp-1.apk

As you can see the second line is: Invalid name: 'search_‌country_name'

This is one of my string names in String.xml

So I delete this string and comment all referenced codes

Then I delete the package name folder in /data/data (if you are using a actual device you should have root access , if you are using emulator just wipe data before opening emulator or make a new AVD)

Now the problem is solved!

You can easily continue coding!

Answer 4

There is already a data directory with the name of package you are trying to install with a different UID assigned. Get a root access and then try removing the already existed directory with the following command in cmd

  rm -r /data/data/com.your.package

Or try to rename your application package to run it on your device.

Answer 5

This solution worked for me:

1. Put your APK to the device's storage/sd card

2. adb shell pm install -l -r "/sdcard/<apk_filename>.apk"
